Click Here for excellent thoughts on God's provision, our definition of need vs. the Biblical definition of need. Here's a couple quotes:
"Our definition of need has been super-sized by our culture of consumption.
So we think that we need not only to eat, but to eat food that we love, and preferably to eat out. We think that we not only need to be clothed, but to wear the latest fashion and have five of everything. We think we need more than just a roof over our heads. We want a bigger house, with a big yard. We think we need multiple cars, four-wheel drive vehicles to drive on paved roads."
"One of the potential spiritual benefits of an economic recession is that as we tighten our budgets, as we change our lifestyle, we can actually begin getting a clearer picture of what we actually need. We have a lot more than we really need."
